Article contents:== Outdated egg! This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for [[/eggref/5/uuid-lib|the CHICKEN 5 version of this egg]], if it exists. If it does not exist, there may be equivalent functionality provided by another egg; have a look at the [[https://wiki.call-cc.org/chicken-projects/egg-index-5.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. [[tags: egg]] == uuid-lib OSF DCE 1.1 UUID [[toc:]] == Documentation Wrapper for {{uuid/uuid.h}} procedures on MacOS X, and Linux. === Predicates ==== uuid? <procedure>(uuid? UUID) -> boolean</procedure> Is {{UUID}} a uuid? ==== uuid-null? <procedure>(uuid-null? UUID) -> boolean</procedure> Is {{UUID}} the null uuid? ==== uuid-compare <procedure>(uuid-compare UUID1 UUID2) -> fixnum</procedure> Returns {{-1}}, {{0}}. or {{1}} for the comaprison of {{UUID1}} and {{UUID2}}. ==== uuid=? <procedure>(uuid=? UUID1 UUID2) -> boolean</procedure> Are {{UUID1}} and {{UUID2}} equal? ==== uuid<? <procedure>(uuid<? UUID1 UUID2) -> boolean</procedure> Does {{UUID1}} order below {{UUID2}}? ==== uuid>? <procedure>(uuid>? UUID1 UUID2) -> boolean</procedure> Does {{UUID1}} order above {{UUID2}}? ==== uuid<=? <procedure>(uuid<=? UUID1 UUID2) -> boolean</procedure> Does {{UUID1}} order below or the same as {{UUID2}}? ==== uuid>=? <procedure>(uuid>=? UUID1 UUID2) -> boolean</procedure> Does {{UUID1}} order above or the same as {{UUID2}}? === Operations ==== uuid-clear! <procedure>(uuid-clear! UUID) -> uuid</procedure> Returns the {{UUID}} set to the null-uuid. ==== uuid-copy <procedure>(uuid-copy UUID) -> uuid</procedure> Returns a copy of the {{UUID}}. ==== make-uuid <procedure>(make-uuid [VARIANT]) -> uuid</procedure> Returns a new uuid. {{VARIANT}} is: ; {{'V1}} or {{'time}} : DCE Version 1 (MAC address) algorithm. ; {{'V4}} or {{'random}} : DCE Version 4 (random) algorithm. ; {{#f}} : The null-uuid. The default. An invalid {{MODE}} is an error condtion. ==== string->uuid <procedure>(string->uuid UUID-STRING) -> uuid</procedure> Returns a new uuid from the external string representation {{UUID-STRING}}. ==== uuid->string <procedure>(uuid->string UUID) -> string</procedure> Returns the external string representation of {{UUID}}. ==== uuid-generate <procedure>(uuid-generate [METHOD]) -> uuid</procedure> Returns a new uuid. {{METHOD}} is: ; {{'random}} : DCE Version 4 (random) algorithm. ; {{'time}} : DCE Version 1 (MAC address) algorithm. ; {{#f}} : DCE V4 if a high-quality random device available, otherwise DCE V1. The default. An invalid {{METHOD}} is an error condtion. ==== uuid-parse <procedure>(uuid-parse UUID-TEXT) -> uuid</procedure> Returns a new uuid from the external string representation {{UUID-TEXT}}. ==== uuid-unparse <procedure>(uuid-unparse UUID [CASE]) -> string</procedure> Returns the external string representation of {{UUID}}. {{CASE}} is {{#f}} (the system dependent local default), {{'upper}}, or {{'lower}}. Default is {{#f}}. An invalid {{CASE}} is an error condtion. == Usage <enscript language=scheme> (require-extension uuid-lib) </enscript> == Notes * The {{uuid?}}. {{uuid-null?}}, {{uuid-compare}}, {{uuid=?}}, {{uuid<?}}, {{uuid>?}}, {{uuid<=?}}, {{uuid>=?}}, {{make-uuid}}, {{uuid-copy}}, {{uuid-clear!}}, {{string->uuid}}, {{uuid->string}} share the same signature as the corresponding routines in the ''uuid-ossp'' extension. * When a UUID argument is not of the expected type the routines will silently fail by returning {{#f}}, no matter what the declared return type. This may change in the future. == Author [[/users/kon-lovett|Kon Lovett]] == Version history ; 1.5.0 ; Add types. ; 1.4.1 : Explicit libuuid for linux. ; 1.4.0 : Added {{make-uuid}}, {{string->uuid}}, {{uuid->string}}. Dropped use of "uuid-lib-c-api.scm" since undocumented. Deprecated {{uuid<>?}}. ; 1.3.0 : Exposed {{uuid-compare}}. ; 1.2 : Hello. == License Copyright (C) 2010 Kon Lovett. All rights reserved.
